The issue is linked to an older version of server BIOS having a conflict with the Extended Display Identification Data (EDID) supplied by the KVM.

Resolution

Disabling one of the VGA ports, or upgrading server BIOS to the most recent revision can resolve the issue. The next steps would be to set the BIOS setting for "embedded video connection" to "Always enable". Schneider Electric will not be able to assist with updating server BIOS - it is recommended before installing anything to a server that you speak with the server manufacturer first.

Update: Many HP G10 servers can still display a black screen even if the above changes are made. A hardware revision is being made to KVMXXX server modules, and this article will be updated when new information on the update is available.
